How to Sharpen a Ceramic Knife: Simple Instructions

At first glace, ceramic knives seem so sharp, it’s hard to believe they even need sharpening. But like any knife, they will eventually dull. Keeping a ceramic blade sharp takes a little effort, but it isn’t difficult and well worth the effort. Here are some simple instructions for sharpening a ceramic knife.

What You’ll Need

  • Ceramic knife
  • High quality knife sharpener
  • Protective gloves (optional)
  • White Rotating Honing Rod (optional)

Hand Sharpening

If you’re sharpening a ceramic knife by hand, you will need a high quality knife sharpener designed for ceramic blades. To get started, fasten the sharpener securely in a vice or clamp. Then begin by slipping the ceramic blade into the coarsest grit guide on the sharpener.

Using a steady, firm motion, draw the blade back across the sharpener towards you, applying medium pressure.

Switch to the next guide and repeat the same motion the same number of times. Be sure to alternate the side you sharpening each time. Continue this process until you’ve completed each guide.

Machine Sharpening

If you have access to a professional knife sharpening machine, you can sharpen your ceramic knife in a short amount of time. To use the machine, put on protective gloves and place the ceramic knife in the machine with the blade facing away from you. Slowly press down on the blade, and slowly pull it across the sharpener as it rotates.

Once you’ve sharpened each side a few times, use a white rotating honing rod to finish sharpening the blade.


  • It’s best to sharpen a ceramic knife as soon as you notice it’s dulling.
  • Protect your hands and keep a firm grip on the blade when sharpening.
  • Follow the manufacturer’s instructions. Do not exceed the number of times they recommend sharpening.

With these simple instructions, you will be able to sharpen a ceramic knife with ease. Just remember to wear protective gloves and take your time. With practice, you’ll find that keeping your ceramic knife sharp is quick and easy.
